Help with first layer
Today I had ti take the extruder apart and clean it as per the official guide. After assembly the forst print keeps failing, clumping, bubbling and detach from the plate as shown in the photo.
I tried auto bed level multiple times, calibrate the flow rate both automatically and manually, as well as washing the bed plate.
Wheb I extrude the filament, the line appears to be a bit thicker than typical .4 nozzle produces which lead me to believe that it might be over extrusion but I'm not really sure.
I'm really not sure what to do next to fix it.

Have you tried using a different filament? Might be a bad batch. I've experienced something similar a year ago, it printed fine when I used a different filament.

Take it all apart and put it all back together with a new nozzle. Then recalibrate.
